 // TimeZoneMonitor watches the system time zone, and notifies renderers
 // when it changes. Some renderer code caches the system time zone, so
 // this notification is necessary to inform such code that cached
 // timezone data may have become invalid. Due to sandboxing, it is not
 // possible for renderer processes to monitor for system time zone
 // changes themselves, so this must happen in the browser process.
 //
 // Sandboxing also may prevent renderer processes from reading the time
 // zone when it does change, so platforms may have to deal with this in
 // platform-specific ways:
 //  - Mac uses a sandbox hole defined in content/renderer/renderer.sb.
 //  - Linux-based platforms use ProxyLocaltimeCallToBrowser in
 //    content/zygote/zygote_main_linux.cc and HandleLocaltime in
 //    content/browser/renderer_host/sandbox_ipc_linux.cc to override
 //    localtime in renderer processes with custom code that calls
 //    localtime in the browser process via Chrome IPC.
